Introduction

Features of this product

Thank you for purchasing Omron's Uninterruptible Power Supply (UPS).

●

The UPS protects computers and other devices from power failures, voltage variations, in-

stantaneous voltage drops, and surge voltage such as that caused by lightning (a phenomenon in which extraordinary high voltage occurs instantaneously).

●

Under normal conditions, a stable sine wave AC voltage is output by raising the voltage (when

the input voltage is low) or lowering the voltage (when the input voltage is high) according to the input voltage status, in synchronization with commercial power input. In addition, a full-time inverter supply method (high efciency) is employed; when abnormalities in commercial power are detected, such as in a power failure or when there are large changes in voltage, power supply is uninterruptedly shifted to the battery, and sine wave output is continued.

●

Output capacity is 2000VA/1400W for BU2002RWLG, 3000VA/2100W for BU3002RWLG

and 5000VA/3500W for BU5002RWLG.

Notes

When moving the unit from a cold place to a warm place, leave it for several hours before using it.

●

If the unit is promptly turned ON after being moved to a warmer place, condensation may form inside the

unit and cause it to fail.

Charge the battery soon after purchasing the unit.

●

If you do not use the unit for a long time after the purchase, the battery may deteriorate and the battery

may become unusable.

●

The battery can be charged once the AC input plug is connected to commercial power.

Recharge the battery for at least 8 hours every 6 months when the storage temperature is 25°C or less, or every 2 months when the storage temperature is 40°C or less.

●

The battery self-discharges even when it not being used, and it goes into over-discharge state if it is left

for a long period of time. The backup time may become shorter or the battery may become unusable.

●

We recommend keeping the temperature 25°C or less when storing the unit for long periods of time.

●

Turn OFF the unit’s power switch when storing it.

Do not short the output lines of the unit to each other, and do not short the output lines to the ground.

●

The unit may fail.

Do not connect the AC input terminal of the unit to its Power Supply Output terminal during the Battery Mode.

●

The unit may fail.

Do not connect a page printer (such as a laser printer) to the unit.

●

The unit repeatedly and frequently switches between Commercial Power Mode and Battery Mode, which

may shorten the life of the battery.

●

The page printer has a large peak current, so an excess of the connection capacity or a power failure due

to instantaneous voltage drop may be detected.

Do not install or store the unit in a place exposed to direct sunlight.

●

The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.

Do not perform withstand voltage tests.

●

Performing withstand voltage tests may damage the surge absorption element built into the power supply

input circuit.

●

When performing an insulation resistance test, use the 400 VDC range.

Before stopping the commercial power to the unit, turn OFF the power switch of the unit.

●

The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery

Mode, the battery life may be signicantly shortened.

If this unit is used for an inductive device such as a coil or motor, check the operation beforehand.

●

With some types of devices, the effect of inrush current may cause this unit to stop operating properly.

Explanation

Usual operation

●

You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when

stopping the connected system. Choose whichever operation method is more convenient. We recommend turning OFF the power switch when you do not use connected devices for a long time.

●

The battery can be charged once the unit is connected to a commercial power source.

Quitting Battery Mode

●

If a power failure lasts for an extended period of time, the battery discharges completely and power output from the unit stops. Shut down your computer after performing appropriate procedures (for example, saving data) while the unit is still supplying power.

Rebooting

●

If the battery discharges completely during a power failure, the output stops. After recovery from the

power failure, the unit automatically restarts and output begins. If you do not want to restart the connected devices, disable the “Settings” - “Boot Settings” - “Auto reboot” setting in the menu on the unit’s LCD, or turn OFF the power switch of the connected devices.

Scheduled operation using the UPS monitoring software

●

When performing scheduled operation in which the UPS is stopped and a device such as a breaker is

used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3 months for the start of the next operation.

If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does

not start. Note that this period reduces to approximately half when the battery needs to be replaced. If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing the start switch. However, if the battery needs to be replaced, you may not be able to start operation.

In this case, replace the battery.

Notes

Check system operation beforehand if the unit is used in combination with a

device whose power supply voltage and frequency uctuate widely, such as a

generator.

●

If the generator’s output voltage/frequency falls out of the input voltage/frequency range, the unit will enter

Battery Mode.

●

Even if the input frequency is within the range, the unit will enter Battery Mode when a rapid change (5

Hz/sec or greater) occurs.

In the event you transfer or sell this unit to a third party, please include all of the documentation that came with the unit. This is to ensure that the unit is used in line with the conditions described in the included documentation.

●

This manual contains important safety-related information. Please read and understand the contents of

the manual before beginning operation.

This unit uses lead acid batteries,

●

Which are a valuable recyclable resource. Please recycle.

Take measures for handling unforeseen accidents, such as data backup and system redundancy.

●

The output may stop when there is a circuit failure in the UPS.

3.Operation

Explanation

Usual operation

●

You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when

stopping the connected system. Choose whichever operation method is more convenient. We recommend turning OFF the power switch when you do not use connected devices for a long time.

●

The battery can be charged once the AC input plug is connected to commercial power.

Quitting Battery Mode

●

If a power failure lasts for an extended period of time, the battery discharges and power output from the

unit stops. Shut down your computer after performing appropriate procedures (for example, saving data) while the unit is still supplying power.

Rebooting

●

If the battery discharges completely during a power failure, the unit stops. After recovery from the power

failure, the unit automatically restarts and supplies power. If you do not want to restart the connected devices, disable the “Settings” - “Boot Settings” - “Auto reboot” setting in the menu on the unit’s LCD, or turn OFF the power switch of the connected devices.

Scheduled operation using the UPS monitoring software

●

When performing scheduled operation in which the UPS is stopped and a device such as a breaker is

used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3 months for the start of the next operation. If you specify a period longer than 3 months, the internal timer

is reset and the scheduled operation does not start. Note that this period reduces to less than half when the battery needs to be replaced. If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing the

Start Switch. However, if the battery needs to be replaced, you may not be able to start operation. In this

case, replace the battery.

Notes

Before stopping the commercial power to the unit, turn OFF the power switch of the unit.

●

The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery

Mode, the battery life may be signicantly shortened.

Take measures for handling unforeseen accidents, such as data backup and system redundancy.

●

The output may stop when there is a circuit failure in the UPS.

This test performs a failure diagnosis on the unit and performs a test to check for battery deterioration.

Use the procedure below to check whether a circuit failure has occurred inside the unit and whether battery replacement is required.

This test is performed if the “Power” switch is ON or performed automatically (You do not have to perform any special operations). Automatic test is performed once every 4 weeks after the unit is connected to a commercial power source and power distribution begins.

If the battery is not charged for at least 24 hours, the self-diagnostic test is not executed immediately.

After charging is complete, it is automatically executed.

(1) When the self-diagnostic test is executed, the Battery Mode starts automatically (No beep

sounds). After the test is complete, the normal operation automatically starts.

(2) If an error message appears on the LCD: Follow the directions for the solutions described earlier in this document.

* This test can also be run from the included UPS monitoring software. For more details, refer to the online help for the UPS monitoring software.

When the beep is sounding, you can suspend it by pressing and holding the beep ESC switch for 0.5 seconds or longer.

(1) Convert the total capacity (power consumption) of the connected devices to watts (W). For the indication of connected devices, check your computer and the rear of the display. The indicator can show values in three different ways: volt-amperes (VA), amperes (A), and watts

(W).

Example 1) 200 VAC, 50/60Hz, 145 W

Example 2) 200 VAC, 50/60Hz, 1.8 A

Example 3) 200 VAC, 50/60Hz, 150 VA

For devices that use the VA or A indication, convert the capacity into W. Multiply the value indi-

cated on devices by the value in the right table for conversion.

(When the power factor is unknown, enter “1”. The power factor usually ranges between 0.6 and 1.)

(2) Add the values converted into W to obtain the total capacity of the connected devices.

(3) Calculate the initial value of the backup time for the total capacity of the connected devices from

the graph below.

●

Graph of backup time (graph of initial values for products that have not been used at 25°C)

The backup time becomes shorter than the graph (table) below when temperature is lower.

●

The smaller the capacity of connected devices becomes, the longer the backup time becomes.

Indication Value

power factor = W

power factor × power supply voltage = W

(1) Connect to commercial power and charge the battery for 8 hours (Charging time is extended 24

hours per unit, if additional battery unit is connected).

(2) Turn ON all devices connected to the unit.

(3) Turn off the commercial power and measure the backup time.

In Battery Mode, measure the time until the unit automatically stops and all displays disappear.

The power supply output of the unit will stop when the battery discharges. Conduct measurement under a condition in which no problem occurs even if the power supply of the connected device stops during the process. Do not conduct measurement if there is a possibility of a failure when the power supply stops.

The lead battery used in the unit has a limited lifespan. (The life varies depending on your storage/use environment and backup frequency.) The nearer the end of the life is, the more rapidly deterioration proceeds.

1. Battery life expectancy (* Not a guaranteed performance)

2. Methods for checking the battery

There are two methods for checking the battery.

• Perform a self-diagnostic test. (See page 30.)

• Measure the backup time. (See page 34.)

By measuring the backup time, the battery life can be determined more accurately.

• When you compare the "initial value of the backup time" you measured and the current backup time, make the capacity of devices connected to the UPS same as when you measured the initial value to make judgment accurately.

When maintaining the connected equipment, turn OFF the unit’s power switch to stop the output, and stop the supply of commercial power.

●

Even if commercial power to the UPS is stopped while it is in operation, the power output of this

unit does not stop and power is supplied from the receptacle.

Do not disassemble, repair, or modify the unit.

●

Doing so may cause an electric shock or a re.

If uid leaks from the unit, do not touch the uid.

●

Doing so may cause blindness or burns.

●

If the uid contacts your eyes or skin, wash it out with lots of clean water and consult your doctor.

Do not throw the unit into re.

●

The lead battery in the unit may explode, or leak dilute sulfuric acid.

Do not insert metal objects into the power supply output receptacles of the UPS.

●

Doing so may result in electric shock.

Do not insert metal objects into the battery connectors. Do not create a short between the connector terminals.

●

Doing so may cause an electric shock.

Explanation

Scheduled operation using the UPS monitoring software

●

When performing scheduled operation in which the UPS is stopped and a device such as a breaker is

used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3 months for the start of the next operation.

If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation

does not start. Note that this period reduces to approximately half when the battery needs to be replaced. If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing

the Start Switch. However, if the battery needs to be replaced, you may not be able to start operation.

In this case, replace the battery.

Start of operation in scheduled operation using the UPS monitoring software

●

To manually start up this unit after it has been stopped by a scheduled operation, turn OFF the power

switch and turn it back ON again.

To stop the unit when it is in operation, turn OFF the power switch.

Auto restart after OS closing processing using the UPS monitoring software

When a power failure occurs, certain PCs (*1) automatically restart immediately after the OS is shut

down by auto shutdown.

In this case, the UPS stops during or after the restart of the PC, which may damage les and the hard

disk. You can avoid this phenomenon by disabling POWER MANAGEMENT in the BIOS settings of the

PC. *1) Certain PC: It is known that this phenomenon occurs for MICRON's Millennia Mme.

Precautions when “setting the UPS to stop automatically” after OS shutdown

●

If, after a power failure occurs, the power is restored while auto shutdown processing is being per-

formed, UPS output stops once after the set time elapses. After shutdown processing is complete, do

not turn ON the computer until the UPS has nished restarting.

Contact signals are included as standard for the unit.

Contact Signal

You can develop your unique system based on the following specications to automate the process

at a power failure. You can perform power-failure processing by allowing the system to detect the backup signal and also perform system shutdown processing by allowing the system to detect the Low battery level signal. Also, by inputting the backup stop signal from the system, you can stop the

UPS with a sufcient battery level to prepare for the next occurrence of a power failure.

7-2-1. Signal output

The UPS has 4 kinds of output signals. The output circuit consists of an open collector circuit using

a photo coupler (a kind of electronic switch).

●

Backup Signal output: BU

Stays ON during backup operation at a power

failure.

●

Low battery level signal output: BL

Goes ON when the battery becomes weak

during backup operation at a power failure.

●

Trouble Signal output: TR

Goes ON when a failure of the UPS occurs or

when the battery life counter expires.

●

Battery Replacement Signal output (WB)

Goes ON when the test determines that bat-

tery replacement is necessary due to deterioration or when the battery life counter goes off-scale.

BU-COM

ON when a power failure occurs

BL-COM ON when the battery is low

TR-COM ON when a power failure occurs

WB-COM

ON when replacing the battery

7-2-2. Signal input

●

Input of the UPS Stop Signal (BS)

When the BS signal is ON (High), the output of the UPS is stopped after the time period specied

in advance has elapsed. The following settings are available on the LCD.

(1) BS Valid Range: "Settings" - "Dry Contact" - "BS Valid Range"

• Always enabled : The BS signal is received either in Commercial Power Mode or Battery Mode.

• Enabled during Battery Mode: The BS signal is received only in Battery Mode.

(2) BS Delay Time: "Settings" - "Dry Contact" - "BS Delay Time"

You can set the amount of time between when the BS signal is received and when the output

of the UPS is stopped.

●

Remote ON/OFF Signal

Remote ON/OFF signals can be used to start

and stop the UPS, by using either an externally connected contact or the ON/OFF status of the open collector circuit.

Connection terminals are at contact signal con-

nector pins 6 ,7.

7-2-7. Precautions and notes for the use of the Contact Signal

Explanation

●

When power is restored after the unit stopped automatically during a power failure, the unit

automatically restarts and supplies power. If you do not want to start the connected devices, turn OFF their switches or set the auto startup setting after recovery from power failure (“Settings”

- “Boot Settings” - “Auto reboot” on the LCD) to “disable”. (See page 32.)

Page 62

Page 63

Perform the checks shown below if the unit is operating abnormally. If the unit continues to operate abnormally, please contact Omron representatives.

Troubleshooting

Problem Check and remedy

The LCD does not appear when the UPS is connected to com

mercial power and the power switch is turned ON.

1. Make sure the AC input is securely connected to commercial power.

2. AC input overcurrent protection is activated and power is cut. (For BU2002R

WLG and BU3002RWLG, the black button has popped up. For BU5002RWLG, it is tilted towards OFF.)

• If the black INPUT PROTECTION button pops up, there are too many con

nected devices or there was a short-circuit with the connected devices. Disconnect all the connected devices, press the black INPUT PROTEC

TION switch (overcurrent protection switch), and turn on the power switch.

• If the status indicator does not display properly after you perform the above operation, there is a problem with the unit.

(See “3-3 Interpreting beeps and displays” on page 29.)

Backup is not possible. The computer stops when a power failure occurs.

The battery may not be fully charged. Perform the test after charging the battery for at least 8 hours. The battery can be charged just by connecting to a wall outlet. The “Power” switch can be either ON or OFF.

Backup is performed too fre

quently. Frequent switching is performed although a power failure does not occur. You hear the sound of switching.

Variations (decrease) in the input power occur frequently. Or, noise may be in

cluded that signicantly distorts the voltage waveform of the input power.

●

Try and check what happens when connecting the unit to a different wall out-

let (commercial power) located some distance away from the device consuming a large amount of power.

●

This problem may occur also when you connect many devices to a plug strip

or extension cord connected to the UPS if it is a long or thin cable.

Does not turn ON when power switch is pressed.

The unit does not start up when the input power supply voltage/frequency is abnormal. (“AC I/P abnormal” is displayed on the LCD.) Check the voltage and frequency of the input power supply.

See also

A. Specications Input voltage range, Input frequency see Page 48.

The display is abnormal.

●

The display is unstable.

●

White lines occur.

●

Noise increases.

The probable cause is noise that occurs inside the UPS.

●

Ground all devices connected to the UPS. Connect them to a wall outlet

(commercial power) for 3-pin plugs or connect their Grounding Terminal to the Grounding Terminal of a wall outlet.

●

This problem may occur when power cords are long or placed closely or

when the UPS and devices to be backed up are placed closely. Rearrange them.

●

If the UPS or devices connected to the UPS are contained in a metal rack, at-

tempt to ground the rack itself.

The battery replacement lamp lights up or blinks, and the beep

er sounds at 2-second intervals.

●

When the battery replacement lamp blinks: Judged as battery deterioration

by self-diagnosis test. Replace the battery as only the short backup operation time is available.

See also

4-2 Self-diagnosis test → page 30

●

When the battery replacement lamp is ON: Battery life counter went off-scale.

The life of the battery has expired. Replace the battery.

“Overload” is displayed. There are too many connected devices. Reduce the number of connected de

vices until the error is resolved.

“Over load time out” is displayed. Output stopped due to exceeded connection capacity.

Turn OFF all power to the unit and connected devices, and reduce the number of connected devices. Then, turn the power to the unit and connected devices back ON and check whether the error is resolved.
